Is it bad to set the WiFi settings for Raspberry Pi 3 in BLE?

Thank you for your help.

Raspberry Pi 3 is convenient with WiFi and BLE built into the board.However, unlike wired LANs, wireless LANs require SSID specification and password entry.Specifically, you must edit the /etc/wpa_supplicant/wpa_supplicant.conf file.Typically, you can connect the keyboard to the display to configure your wireless LAN, and then use ssh to operate without a display or keyboard.

However, it was inconvenient, so I came up with the following idea.Wouldn't it be convenient to search for BLE devices on your smartphone or PC and then set up an SSID or password via BLE?Then you can connect to the Internet without a keyboard or display.

I think this is a common idea, but I couldn't find such a case when I searched various ways in Japanese and English.I'm not used to dealing with BLE at all, so I'm worried that I can't do this or shouldn't do it, but I'd appreciate it if you could give me your opinion.If you are able to do so without any technical problems, I would appreciate it if you could provide me with helpful information (URL, books, etc.).

The SSID configuration here is not a new Raspberry Pi configuration, but rather a Raspberry Pi developed at home, which is expected to be brought to a friend's house somewhere.In other words, when Raspberry Pi is powered on, a pre-created program (which appears to have a lot of node.js) rewrites wpa_supplicant.conf or starts with the required permissions (root?) to restart the service and waits for a connection from your smartphone.

Thank you for your cooperation.

I haven't tried it yet, but I found something called Wi-Fi SmartConfig.

This is looking at how other IoT hard drives solve similar problems, and is described in Sansaire Delta product description
